ckecking heads for head gasket knowledge


Recommended Posts

Hi guys. So I am workng on a block tht never fails to dissapoint me. I just trashed a hgasket because on the first sequence of torgue down I stripped out my 2nd bolt hole- when pulling the head back up it disintegrated due to the sealer I put down (some thin copper color brush on stuff)

 

1. How many of you guys use sealer?

 

2. what has the oil passage o- ring commonly looked like in your hg kits?

The kit I initially purchased came w/ an assortment of rings, none of which seemed to jump out at me as being the right one-

When I went to dealer for o-ring, they gave some kinda nitrile coated ring w/ a crush washer in it. It does not fit into the after market hgasket- which had a copper ring already fastened on the hg on the puch out for the oil passage. I am starting to think that this kinda gasket is supposed to have its own crush washer - have you guys seen this before?

 

The replacement aftermarket hg I picked up at the local action auto- the one they gave me only has a straight punch out where the oil passage reisdes- again too small for the dealer or-ring. Can I substitute any proper sized oil resistant o-ring?

 

As usual, Im long winded. If you got this far thanks- I would really like to put this thing together once and rightly. Yes, I know Im inviting trouble w/ aftermarket hgaskets.

i would say make the gasket fit the stock oring. or just use what the aftermarket gasket gave you. i bet they would both seal up fine. head bolts should only have a thin coating of oil on them, when you put them on. i mean thin. most guys blow the holes out with compressed air to assure the bolt holes arent full of oil, to throw off the torque measurements. hope that helps, some

Sorry I didn't see this earlier.

We would prefer to use the Genuine o-ring. They fit right and last longer. Unfortunately, that also means that I really don't have an answer to your headgasket question, because we won't use aftermarket there either.

Yes, we use a sealer: a light coating of Permatex Spray A Gasket Copper.

Doing a turbo block, eh? Did you remember to clean out the bolt holes? Wirebrush the bolt threads?

 

Sorry I couldn't be more help. Bottomline: if you want to put it together "once and right", messing around with trying to make stuff fit isn't gonna cut it.
